Divisible by 5 is discussed below:
A number is divisible by 5 if its units place is 0 or 5.
Consider the following numbers which are divisible by 5, using the test of divisibility by 5: 50, 75, 90, 165, 120.
(i) 50
In 50, the unit’s place digit is 0.
Hence, 50 is divisible by 5.
(ii) 75
In 75, the unit’s place digit is 0.
Hence, 75 is divisible by 5.
(iii) 90
In 90, the unit’s place digit is 0.
Hence, 90 is divisible by 5.
(iv) 165
In 165, the unit’s place digit is 5.
Hence, 165 is divisible by 5.
(v) 120
In 120, the unit’s place digit is 0.
Hence, 120 is divisible by 5.
Consider the following numbers which are not divisible by 5, using the rules of divisibility by 5: 54, 77, 106, 127, 152.
(i) 54
In 54, the unit’s place digit is 4.
Hence, 54 is not divisible by 5.
(ii) 77
In 77, the unit’s place digit is 7.
Hence, 77 is not divisible by 5.
(iii) 106
In 106, the unit’s place digit is 6.
Hence, 106 is not divisible by 5.
(iv) 127
In 127, the unit’s place digit is 7.
Hence, 127 is not divisible by 5.
(v) 152
In 152, the unit’s place digit is 2.
Hence, 152 is not divisible by 5.
